摘要： A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sense element. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The capacitance sense interface monitors a rate of change of the measured capacitance values and rejects an activation of the capacitance sense element as a non-touch event when the rate of change of the measured capacitance values have a magnitude greater than a threshold level, indicative of a maximum rate of change of a touch event.

摘要： A technique for recognizing and rejecting false activation events related to a capacitance sense interface includes measuring a capacitance value of a capacitance sensor within the capacitance sense interface to generate a measured capacitance value. The measured capacitance value is analyzed to determine a baseline capacitance value for the capacitance sensor. The baseline capacitance value may be updated based at least in part upon a weighted moving average of the measured capacitance value. The measured capacitance value may also be analyzed to determine whether the capacitance sensor was activated during a startup phase and to adjust the baseline capacitance value in response to determining that the capacitance sensor was activated during the startup phase.

摘要： Some embodiments provide a system that determines a battery chemistry for a battery in a peripheral device. During operation, the system determines a first voltage of the battery at a first time and a second voltage of the battery at a second time. The first voltage and the second voltage are then compared to one or more predetermined battery usage profiles to determine the battery chemistry.

摘要： A touch-sensitive depressible button with multiple depression thresholds is provided. When the button is depressed to a first depression threshold, the touch sensor can be switched from a low-power, non-sensing state to a sensing state. When the button is depressed to a second depression threshold, the touch sensor can sense the touch context and input can be generated based on the depression and the touch context. In this way, the touch-sensitive depressible button with multiple depression thresholds can facilitate timely switching of the touch sensor to a sensing state.

摘要： A touch sensing system is disclosed that can include a firmware module stored in memory and executed at run time to store values into a hardware register for configuring various parameters of capacitive sensing system to reduce quantization and scan noise, reduce interference with neighboring electronics, and avoid noise aggressors. In addition, a serial peripheral interface (SPI) can be employed to allow a host controller to access information about the performance of touch controller and send communications back to touch controller to make run-time changes to the parameters of touch controller.
